MoviePy - 在视频剪辑上应用调整大小效果

在本文中，我们将了解如何在 MoviePy 中对视频文件剪辑应用调整大小效果。 MoviePy 是一个用于视频编辑的Python模块，可用于视频和 GIF 的基本操作。我们可以借助resize方法调整视频的大小来调整视频剪辑的大小，resize filter 是应用在它上面的过滤器类型。

In order to do this we will use fx method with the VideoFileClip object

Syntax : clip.fx( vfx.resize, width= 280)

Argument : It takes vfx object and width or height as optional argument

Return : It returns VideoFileClip object

下面是实现

# Import everything needed to edit video clips
from moviepy.editor import *
   
# loading video dsa gfg intro video
clip = VideoFileClip("dsa_geek.webm")
   
# getting only first 5 seconds
clip = clip.subclip(0, 5)
   
# applying resize filter
final = clip.fx( vfx.resize, width = 280)
  
# showing final clip
final.ipython_display()

输出 ：

Moviepy - Building video __temp__.mp4.
Moviepy - Writing video __temp__.mp4

                                                                                                                       
Moviepy - Done !
Moviepy - video ready __temp__.mp4

另一个例子

# Import everything needed to edit video clips
from moviepy.editor import *
  
# loading video gfg
clip = VideoFileClip("geeks.mp4")
  
  
# getting subclip from it
clip = clip.subclip(0, 5)
  
# applying resize filter
final = clip.fx( vfx.resize, width = 280)
  
# showing final clip
final.ipython_display()

输出 ：

Moviepy - Building video __temp__.mp4.
MoviePy - Writing audio in __temp__TEMP_MPY_wvf_snd.mp3
                                                                                                                       
MoviePy - Done.
Moviepy - Writing video __temp__.mp4

                                                                                                                       
Moviepy - Done !
Moviepy - video ready __temp__.mp4
